## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402vid-thumbnail-creation-7926dde9 -d '<json body>'
```

Example prompt: Can you create a YouTube thumbnail for my gaming channel video at https://youtube.com/watch?v=abc123 — target it at the gaming niche and use an action-packed style?

## When to prefer this

Choose this endpoint when you need to generate a ready-to-use YouTube thumbnail image, especially when you can derive the concept directly from an existing video URL or photo. It is distinctly useful for AI agents managing YouTube content pipelines that need per-call, pay-as-you-go thumbnail generation without a subscription, and when niche-specific visual targeting matters.

## Known failure modes

- Invalid or inaccessible video_url returns an error or empty concept
- Malformed base64 in image_b64 causes processing failure
- No input provided (no video_url, image_url, image_b64, or image_prompt) results in an error
- Payment failure via x402 protocol prevents call from completing
- Image generation model timeout or unavailability returns a service error
